# Chart Element Interpretation

`POST /interpret/element`

## Query parameters

- `lang` 'uk' | 'en' | 'de' | 'ru' | 'pl' | 'es' | 'pt' | 'fr' | 'it' | 'nl' | 'cs' | 'ro' | 'hu' | 'el' | 'tr' | 'ar' | 'hi' | 'ja' | 'ko' | 'vi' | 'id'

## Headers

- `Accept-Language` 'uk' | 'en' | 'de' | 'ru' | 'pl' | 'es' | 'pt' | 'fr' | 'it' | 'nl' | 'cs' | 'ro' | 'hu' | 'el' | 'tr' | 'ar' | 'hi' | 'ja' | 'ko' | 'vi' | 'id'

## Request body

- InterpretElement — Birth data for a single natal chart. Required: date (YYYY-MM-DD), time (HH:mm:ss). Coordinates are latitude and longitude in decimal degrees, plus timezoneOffset in hours from UTC; the short forms lat, lon, lng and tz are rejected with 400 INVALID_FIELD. Omitting the coordinates is not the same as skipping them: houses, angles and everything derived from them are then computed for 0°N 0°E at UTC, which is a wrong answer rather than a neutral default.
